The present invention has relation to elevators, and it consists in the diiferent parts and combination of parts hereinafter described, and particularly pointed out in the claims.

Like numbers represent corresponding parts in all of the figures of the drawings.

In the accompanying drawings l, represents the toothed bars, which are located upon the inner sides of the elevator shaft, and are of a length to correspond with the length of travel designed to be given to the elevator proper. If the bars l are to be of considerable length I prefer to form said bars in sections, and place the sections together so as to form continuous toothed bars from the top to the bottom of the elevator shaft in the event the car is to travel that distance. The

toothed bars 1, are to be so arranged that they will be parallel to each other throughout their entire length.

The elevator frame which is to be located below the car may consist of the bars 2, 3, 4. and 5, which bars are preferably located and arranged substantially as shown in Figs. l

and 2, which arrangement is the best for ar- 5 5 ranging the different parts to be attached to said frame. The elevator car is to be attached to the bar 2 in any convenient manner, and may be of any desired kind or style,

reference being had to the purpose for which 6o the car is to be used.

To the bars 4, are journaled the shafts 6, which shafts are located substantially as shown in Figs. 1, 2, and 6, and as shown said shafts are provided with the toothed wheels means of `the boxes 9, which boxes are at- 7o tached in any convenient and well known manner to the bars 5 or their equivalents. The shafts 8, are provided at their inner ends with the toothed wheels 10, which toothed wheels are so located and arranged that their teeth will interlace or mesh with the teeth of the toothed wheels 7.

The shafts 6 and 8 are held in proper position with reference to each other by means of the socket connections 11, and the pins l2, 8o

said parts being located and arranged substautially as shown in Fig. 2. To the outer ends of the shafts 8, are securely attached in any convenient and well known manner, the

worm-disks 13, which worm-disks are provided upon their faces with the worms or screw-threads 14, which screw-threads may be of any desired pitch, reference being had to the use to which the elevator proper is to be put. In the drawings the worms or screwthreads 14C are shown single, but it will be understood that they may be doubled if so desired, inasmuch as the same arrangement of the different parts can be employed in-either event. threads i4. to engage the teeth of the toothed bars l only upon one side of their horizontal centers, said disks are set atan angle, as illustrated in Figs. l and 2, thereby allowing the reverse part of the disks to be disengaged rco from the teeth upon the bars l.

For the purpose of providing a means for For the purpose of causing the screw- 9 5 inclining the worm-disks 13, the shafts 8 are also inclined to correspond with the inclination of the worm-disks, and in order to conneet the inclined shafts 8 with the horizontal shafts 6, the toothed wheels 7 and 10 are provided, and the teeth so arranged that said wheels can stand or set at an angle to each other, and at the same time a sufiicient number of the teeth interlace to communicate rotary motion to the inclined shafts 8, and their worm disks 13.

To the shafts 6 are securely attached the cog wheels 15 and 16, which wheels are so located and arranged that they will mesh with each other, and thereby communicate rotary motion to all of the Worm-disks 13, and for the purpose of causing the Worm-disks to rotate in unison the cog wheels 15 and 16 are of the saine size and provided with an equal number of teeth.

It will be understood that the cog wheels 15 and 16, will rotate in opposite directions, thereby causing the respective worm-disks to rotate in opposite directions, and for the purpose of causing all of the screw-threads 14 to act alike, each set of the worm-disks must be provided with right and left hand screwthreads; that is to say if the upper disks 13 are provided with right hand screw-threads the lower disks must be provided with left hand screw-threads or vice versa.

To the bar 2 or its equivalent is attached the notched segment 17, which notched segment is provided with the notches 18, 19 and 20, which notches are for the purpose hereinafter described.

For the purpose of providing a means for pivotally attaching the lever 2l, and at the same time connecting the outer end of the segment 17, the arm 22 is provided, which arm is securely attached to the bar 2 or its equivalent, said arm having journaled thereto the shaft 23, to which shaft is securely attached the arm 24, and to the outer of said arms is attached the connecting rod 25, which connecting rod is extendeddownward and connected to the collar 26, said collar beingloosely mounted upon the shaft27, which shaft is held in proper position by means of the arms 28, which arms are pivotally connected to the cross bar 29, said cross-bar being securely attached in any convenient and well known manner to the bars 5 or their equivalents.

To the shaft 27, is securely attached the cog Wheel 30, which cog Wheel is located in true alignment with the cog Wheels 15 and 16, and is so located for the purpose hereinafter described. To the outer end of the shaft 27 is attached a pulley 31, which pulley is for the purpose of communicating rotary motion to the shaft 27, by means of the cable 32 or its equivalent.

In use the power shaft 33 is preferably located at the bottom of the elevator shaft proper, and is properly connected by belt or otherwise to a motor of any desired kind or style. Upon the shaft 33 is located and securely fixed the Wheel 34, and directly over the Wheel 34 is located the pulley 35, which pulley is located at the top or upper portion ot' the elevator shaft.

The cable 32 is extended from the wheel 34 upward and over the Wheel 35, and thence downward and under the wheel 31, thence upward and over the idler 36, and thence down- Ward under the Wheel 34. The object and purpose of locating the cable 32, as illustrated in Fig. 5, are to provide a means for covering a sufficient amount of the periphery of the wheel 31 to prevent the cable from slipping upon the periphery of the wheel 31.

When it is desired to stop the car at any desired point in the elevator shaft, the sliding bar 37 is set in the notch 19, which disengages the cog wheel 30, from the wheels 15 and 16, at which time the motor is free to run Without communicating rotary motion to any of the parts, except the wheels 31, the cog wheel 30, and the different pulleys over and around which the cable passes.

When it is desired to impart motion to the elevator car or carriage, the sliding bar 37 is disengaged from the notch 19 after which the lever 21 is moved so as to engage the sliding bar 37 With one of the notches 18 or 20, reference being had to the direction the carriage is to be moved,which movement engages the cog wheel 30 with one of the wheels 15 or 16, thereby communicating rotary motion to said Wheel 15 or 16 and at the same time rotary motion is communicated to the worm disks 13, which rotary motion of the disks 13 ele vates or lowers the carriage, reference being had to the direction of motion given to the disks. It will be understood that by shifting the wheel 30 from one Wheel to the other of the wheels 15 or 16 the direction of motion of the disks 13 will be changed.

It Will be understood that reversing the position of the lever 2l will reverse the motion of the Worm-disks 13, thereby reversing the motion of the elevator carriage.

It will be understood that as the lever 21 is moved the shaft 27 Will follow the movements of said lever by means of the arm 24, and the connecting rod 25, said shaft 27 describing the arc of a circle, the center of which is the center of the cross-bar 29.

It will also be understood that the cog wheel 30 and the wheel 31 will follow the movements of the shaft 27. For the purpose of regulating the tension of the cable 32, the pulley 38 is provided, which pulley is journaled to the bottom or lower end of the arm 39; the opposite end of said arm being provided with the counter-Weight 40.

The toothed bars 1, are each provided with the grooves 41, which grooves are located substantially as shown in Figs. 3 and 4, and are for the purpose of receiving the notched plates 42 and the traveling wheels 43. The object and purpose of providing the grooves is to prevent any accidental displacement of the worm disks 13, and at the same time caus IIO ing the frame carrying the gearing to corn municate rotary motion to the worm disks to move up and down in true alignment with the toothed bars 1.

For the purpose of preventing the worm `disks13 from springing so as to disengage their screw-threads from the teeth of the bars 1, the backing wheels 44 are provided, which backing wheels are located substantially as shown in Figs. 1 and 2.

For the purpose of providing a means for properly lubricating the screw-threads 14, the worm disks 13 are provided with the wooden or porous disks 45, which disks may be provided with a screw-thread corresponding in size and pitch with the screw-threads formed upon the worm disks 13, but this is not absolutely necessary as the only object in providing the wood disks 45, is to provide a means for allowing oil to percolate through said disks and find its way onto the screw-threads 14.

The cable 32 is simply for the purpose of communicating rotary motion to the worm disks 13 by means of the gearing described, and hence a belt may take the place of the cable, inasmuch as the elevator car or carriage is not supported by the cable, and if in the event the cable or belt should break from any cause the elevator car or carriage will not drop or fall, said car being held by means of` the toothed bars 1, and the worin disks 13, thereby providing an elevator that will be absolutely safe.

The inclined shafts 8, are formed in pairs or sets, and one set located `above the other, thereby providing two sets of worm disks, located one above the other.

In use it will be understood that the frame carrying the gearing may be properly inclosed for the purpose of preventing accidents.
